First email after registering my Fitbit zip device that I won in an Pepsi promotion at work. I’m not the biggest fan of “badges” in the gamification sense, but milestone emails like this one are okay for me. It serves as both confirmation that your Fitbit is set up correctly and is tracking your progress towards your goals as well as encouragement to keep going. I could see this being extremely valuable to owners who are on the fence about working out/exercising every day, especially during the first weeks of ownership. A little like a new gym membership. Having social tools here probably helps those same people share that they’re actually doing what they said they would do.
